Multiple permissions and ask again on denial

I want to make an app which asks user for two permissions- READ_CALL_LOG and READ_CONTACTS. Now if the user denies READ_CALL_LOG then it should show a warning which should have a button that asks the user to grant permission again. When that button is clicked the user is asked again to grant READ_CALL_LOG permission. When the user grants READ_CALL_LOG permission he is taken to READ_CONTACTS permission. If he denies READ_CONTACTS permission then again it should show a warning which should have a button that asks the user to grant permission again. When that button is clicked the user is asked again to grant READ_CONTACTS permission. I don't want the user to be navigated to Settings if he denies. I have tried this code:
public class MainActivity extends AppCompatActivity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/*if(((ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG)== PackageManager.PERMISSION_DENIED)&&(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)== PackageManager.PERMISSION_DENIED))||((ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG)!= PackageManager.PERMISSION_GRANTED)&&(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)!= PackageManager.PERMISSION_GRANTED)))
requestPermission();*/
if(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG)== PackageManager.PERMISSION_DENIED)
{
requestCallLogsPermission();
}
if(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)== PackageManager.PERMISSION_DENIED)
{
requestContactPermission();
}
}
private void requestCallLogsPermission()
{
if(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG)!= PackageManager.PERMISSION_GRANTED)
{
Dexter.withActivity(MainActivity.this).withPermission(Manifest.permission.READ_CALL_LOG).withListener(new PermissionListener()
{
#Override
public void onPermissionGranted(PermissionGrantedResponse response)
{
Toast.makeText(MainActivity.this, "Call Logs Permission is granted !", Toast.LENGTH_SHORT).show();
//if((ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)== PackageManager.PERMISSION_DENIED)||ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)!= PackageManager.PERMISSION_GRANTED)
requestContactPermission();
}
#Override
public void onPermissionDenied(PermissionDeniedResponse response)
{
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Permissions");
builder.setMessage("Permission is required");
builder.setCancelable(false);
builder.setPositiveButton("Understood, I am ready to give the permissions required", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which)
{
requestCallLogsPermission();
}
}).show();
}
#Override
public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
token.continuePermissionRequest();
}

}
}
private void requestContactPermission()
{
Dexter.withActivity(MainActivity.this).withPermission(Manifest.permission.READ_CONTACTS).withListener(new PermissionListener() {
#Override
public void onPermissionGranted(PermissionGrantedResponse response) {

}
#Override
public void onPermissionDenied(PermissionDeniedResponse response) {

builder.setCancelable(false);
builder.setPositiveButton("Understood, I am ready to give the permissions required", new DialogInterface.OnClickListener() {

}).show();
}
#Override

}
}).check();
}
}

You can try this method:
1.) Setting up permissions:
String[] permissions = {
android.Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.CAMERA
}; // Use the permission you need
2.) -Check and request if not already permitted:
onCreate() {
if (!checkPermissions()){
ActivityCompat.requestPermissions(this, permissions, 1);
}
}
private boolean checkPermissions() {
for (String permission: permissions){
if (ActivityCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED){
return false;
}
}
return true;
}
3.) Check for denial status and keep asking till all permissions are granted:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
boolean allGranted = true;
for (int result: grantResults){
if (result == PackageManager.PERMISSION_DENIED){
allGranted = false;
}
}
if (!allGranted){
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA) ||
ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_EXTERNAL_STORAGE))
{
// Here do whatever you want once the user denies
final String[] mPermissions = permissions;
AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Alert!");
alertDialog.setMessage("Please allow the permissions!");
alertDialog.setCancelable(false);
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
ActivityCompat.requestPermissions((MainActivity.this), mPermissions, 1);
dialog.dismiss();
}
});
alertDialog.show();
}
else {
Log.d(TAG, "PERMANENTLY DENIED");
AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Alert!");
alertDialog.setMessage("All permissions are necessary for app to run. Goto settings and grant them.");
alertDialog.setCancelable(false);
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));
dialog.dismiss();
}
});
alertDialog.show();
}
}
}

cannot resolve symbol REQUEST_PERMISSIONS and myMethod() in android studio this is my code

if (ContextCompat.checkSelfPermission(MainActivity1.this,
Manifest.permission.WRITE_EXTERNAL_STORAGE) + ContextCompat
.checkSelfPermission(MainActivity1.this,
Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale
(MainActivity1.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) ||
ActivityCompat.shouldShowRequestPermissionRationale
(MainActivity1.this, Manifest.permission.READ_CONTACTS)) {
Snackbar.make(findViewById(android.R.id.content),
"Please Grant Permissions",
Snackbar.LENGTH_INDEFINITE).setAction("ENABLE",
new View.OnClickListener() {
#Override
public void onClick(View v) {
ActivityCompat.requestPermissions(MainActivity1.this,
new String[]{Manifest.permission
.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_CONTACTS},
**REQUEST_PERMISSIONS**);
}
}).show();
} else {
ActivityCompat.requestPermissions(MainActivity1.this,
new String[]{Manifest.permission
.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_CONTACTS},
**REQUEST_PERMISSIONS**);
}
} else {
//Call whatever you want
**myMethod();**
}

That is the request code you need to pass to the request permisson method,
once user grants/deny the permissions,call back method
onRequestPermissionsResult will be called with permission result.
public static final int REQUEST_PERMISSIONS = 100;//Any integer
ActivityCompat.requestPermissions(MainActivity1.this,
new String[]{Manifest.permission .WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_CONTACTS}, REQUEST_PERMISSIONS);
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions,
#NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (grantResults.length > 0
&& grantResults[0] == PackageManager.REQUEST_PERMISSIONS) {
goToCamera(null);
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
}

REQUEST_PERMISSIONS is an integer value that specifies your request code for some permission. Write following line at the top your activity.
private static final int REQUEST_PERMISSIONS=1232;//This can be any integer value and field name can also be changed

shouldShowRequestPermissionRationale not working as expected

I'm working on checking and getting permission from user with API level 23 and above. So here is a confusing thing for me, android.com says:
shouldShowRequestPermissionRationale() method returns true if the app has requested this permission previously and the user denied the request.
If the user turned down the permission request in the past and chose the Don't ask again option in the permission request system dialog, this method returns false
in other side it gives following code for checking permission and request permission if its neccessery
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Manifest.permission.READ_CONTACTS)) {
// Show an explanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
else scope in above example runs if user doesn't allow permission and check Don't Ask Again, Right? So with this code user never being asked for permission at first time run. I tested that code and the result is what I expected.
So How could I request permission for first time run and do something if user previously denied my request and do something if user deny my request and check Don't Ask Again?

You can do the following.
Ask permission every time by only checking that permission is not granted already. Don't handle the "Don't ask again" in this method. (if user checks "Don't ask again" the OS will automatically handle and will not ask for permission again and will give a call back of permission denied)
Handle the ActivityCompat.shouldShowRequestPermissionRationale() in the call back method onRequestPermissionsResult().
Here is my code in which I am asking for permission everytime
public void checkAndAskCameraPermission() {
if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(context,
new String[]{Manifest.permission.CAMERA}, CAMERA_PERMISSION_REQUEST_ID);
}
}
This is how I handles the call back
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case CAMERA_PERMISSION_REQUEST_ID: {
if (!ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)) {
// Do something if permission is not granted and the user has also checked the **"Don't ask again"**
} else if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_DENIED) {
// Do something if permission not granted
}
}
}
}

first check if the permission is granted then do what you need
else if permission is denied then check weather you should request the permission you need or not through shouldShowRequestPermissionRationale.
if shouldShowRequestPermissionRationale return false then you can just show a message to the user to told them to enable the permission manually.
other then if shouldShowRequestPermissionRationale return true then request the permission and get the result of granting permission in onRequestPermissionsResult
update , this is just a simple code to show the steps:
if (checkSelfPermission == granted){
// do what you want
} else if (shouldShowRequestPermissionRationale == true) {
// you can request the permission you want from the user, then check whether permission granted or not inside onRequestPermissionsResult method
} else {
// here you know the permission is not granted , and also the user check on "Dont ask Again!" checkbox, so all you can to do is just tell the user to enable the permission manually from app permissions through Toast message or any thing else
}

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//initilize your views
if(iscontactsAllowed){
// do your code here
} else {
requestcontactsPermission();
}
}
private void requestcontactsPermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.READ_CONTACTS)) {
//If the user has denied the permission previously your code will come to this block
//Here you can explain why you need this permission
//Explain here why you need this permission
Log.d("scancode", "denied permission before");
}
Log.d("perm", "fourth");
//And finally ask for the permission
ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.READ_CONTACTS}, READ_CONTACTS_CODE /*can be any interge */);
}
private boolean iscontactsAllowed() {
//Getting the permission status
int result = ContextCompat.checkSelfPermission(this, android.Manifest.permission.READ_CONTACTS);
//If permission is granted returning true
if (result == PackageManager.PERMISSION_GRANTED)
return true;
//If permission is not granted returning false
return false;
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {

if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// you have the permission call yur method here
} else {
// permission denied show user why you need it or ask again by calling reuestpermission if you need the permission
}
}

What I have found is that shouldShowRequestPermissionRationale only returns true if the user has denied permission (at least once) and not selected "Don't Ask Again". Meaning, it won't be displayed on the first time the permission is requested either.

How to ask permission (RunTime) again if the user deny for the first time

I want to re ask the permission to the user in the situation if he/she deny for the first time. I have set the permission but my app runs even if I press deny option. I have a code which should do the things which I want to do but I get Cant resolve symbol Snackbar when I hit Alt+Enter it created another activity and remaining -make and -permision_available_camera gets red error.

Try this
Basically here we are trying to read the content from the External Storage. For that, we have to ask the user for runtime permission. If the user allows it's fine, but if the user denies the permission it will display a second dialog/message box until the user accepts the permission
Asking for permission
If the user denies it will display the 'Permission Needed' dialog whenever the user launches the application
If the user presses the OK button it will ask permission again.

Now you can directly check if you have that permission or not,Suppose you want to check for READ_EXTERNAL_STORAGE permission
if (PermissionUtils.checkPermission(RegisterScreenActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE)) {
//Do your work
} else {PermissionUtils.requestPermissions(RegisterScreenActivity.this, "You need to provide storage permission for this service", 101, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE});//ask for permission
}
You can also track its result in onRequestPermissionsResult() methods like
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case 101:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//permission granted, can do your work
} else {
//permission not granted
}
break;
}
}
